Objective / Rules- Complete the grid such that every row and column contains the digits 1 to the size of the grid.- Each row and column contains each digit only once.- A cage clue tells you the answer after the cage values have undergone the specified mathematical operation.- The clue doesn't tell you which way around the digits occur, just the answer to the calculation.- A digit may appear more than once in a cage (which is different to Killer Sudoku).

Keyboard Usage[only when your cursor is in the grid]Note: not all options work on all browsers.A = auto-pencil marks (or click the check box).CTRL + arrows = move around the grid.SHIFT + number = highlight all squares with that number [SHIFT+0 to clear].

CheckingIf you click 'Check' the system will check for incorrect squares. If 'Show mistakes when checking' is checked they will be marked in red. There are two types of error checked for:1. A single number that isn't the same as the solution.2. Multiple numbers that don't contain the solution number.

UniquenessEach puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules.
